Brake wear on other Mazda3 years
No other Mazda3 model year has enough reports of brake wear for a sheet of its own. See every Mazda3 year.
What this problem usually is
Brake reports cover a wide spread of symptoms. Grinding or squealing is common, and so is a pulsing pedal or a shake through the car when stopping. Others describe pads and rotors worn out long before they expected, a brake warning light, or a pedal that goes soft or sinks toward the floor. The most serious ones say the car didn't stop in time.
What got replaced
Owners who name the part that was replaced mention the caliper (8 reports) and the pads and rotors (6 reports).

Is this a known problem?
The manufacturer has sent NHTSA 10 service bulletins or notices for the 2015 Mazda Mazda3 that deal with this problem. Newest first.

What owners wrote
“The parking brake does not disengage even after the recall fix was applied. Mazda refuses to look at it any more as the fix has passed your testing despite it not working.”

Should you keep driving it?
This page can't tell you that. 3 of 26 reports involved a crash and 2 people were hurt. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
